Using Game Genie to play modded saves on PS3

An anonymous user commented here and suggested Game Genie in addition to DISE.

Note: There's a European and US version, and I've confirmed that it allows you to play modded saves on the PS3 (Game Genie only supports Riptide at time of writing). I used the European version for the European version of Riptide.

Game Genie is not free, but it comes with a big bunch of cheats for other games as well.

Rough tutorial

First, you can use the Game-save helper tool and mod your save in DISE, then place your modded save back onto your USB drive (same as before).

Next, start up Game Genie, double-click the game to enter Quick Mode, then tick one of the cheats (e.g. Max Money). After applying the cheat, your save will be uploaded to a remote server, modded and sent back to you.

What's left is copying the save from your USB drive to the PS3 (same as before). :)
